Abstract
ObjectiveMicrosurgical lymphatic vessel transplantation is one of the well-established therapies for lymphedema. Lymphatic vessels are harvested from a healthy thigh and transplanted into lymphedematous limbs to create a lymphatic bypass. Its benefit on lymphatic drainage has already been proven. However, to the best of our knowledge, the effect on the lymphatic function of the donor site has not yet been studied. Our aim was to evaluate the long-term postoperative lymphatic function in the donor site by clinical and scintigraphic examinations and a patient questionnaire. MethodsA consecutive series of 25 women (mean age, 57.2 years) who had undergone follow-up after lymph vessel transplantation to treat secondary lymphedema of the arm comprised the study group. Lymphatic vessel function of the donor site was evaluated by circumferential measurements of the limb and, in nine cases, by lymphatic scintigraphy. Additionally, a questionnaire was used to assess the patients’ pre- and postoperative complaints for the donor limb and quality of life. Separately, the medical records of 100 patients who had undergone lymphatic harvest and been followed up were reviewed for documented signs of lymphatic function of the donor limb. ResultsThe lymphatic grafts were harvested from the thigh (left, n = 9; right, n = 16) and transplanted to bridge the region of lymphatic obstruction in the axilla. The mean follow-up period was 4.5 years after surgery. None of the patients had shown significant changes in the circumference of the donor limb or pathologic findings via lymphatic scintigraphy. None of the patients had reported any impairment in the donor leg or showed symptoms of postoperative lymphedema or erysipelas. ConclusionsOur results have shown that harvesting lymphatic vessels from the thigh for lymphatic vessel transplantation is possible without significant donor site morbidity.
